我正在创建一个 Office 365Addin,它获取整个打开文档的数据。我使用 this 作为参考。
当我第一次和第二次单击“#submit”按钮时,一切正常,但之后就失败了。
据我所知,Document.getFileAsync只允许在内存中存储2个文档。 File.closeAsync 关闭内存上的文档以允许其他文档打开,在我的情况下,它不是返回 sliceCount 0 和大小 0。
File.closeAsync 是否存在错误,或者我是否在文档中遗漏了某些内容?
如有任何帮助,我们将不胜感激。
谢谢你,
function getDocumentAsCompressed() {
Office.context.document.getFileAsync(Office.FileType.Compressed, { sliceSize: 65536 /*64 KB*/ },
function (result) {
if (result.status == "succeeded") {
// If the getFileAsync call succeeded, then
// result.value will return a valid File Object.
var myFile = result.value;
var sliceCount = myFile.sliceCount;
var slicesReceived = 0, gotAllSlices = true, docdataSlices = [];
app.showNotification("File size:" + myFile.size + " #Slices: " + sliceCount);
// Get the file slices.
getSliceAsync(myFile, 0, sliceCount, gotAllSlices, docdataSlices, slicesReceived);
}
else {
app.showNotification("Error:", result.error.message);
}
});}
function getSliceAsync(file, nextSlice, sliceCount, gotAllSlices, docdataSlices, slicesReceived) {
file.getSliceAsync(nextSlice, function (sliceResult) {
if (sliceResult.status == "succeeded") {
if (!gotAllSlices) { // Failed to get all slices, no need to continue.
return;
}
// Got one slice, store it in a temporary array.
// (Or you can do something else, such as
// send it to a third-party server.)
docdataSlices[sliceResult.value.index] = sliceResult.value.data;
if (++slicesReceived == sliceCount) {
// All slices have been received.
file.closeAsync();
onGotAllSlices(docdataSlices);
}
else {
getSliceAsync(file, ++nextSlice, sliceCount, gotAllSlices, docdataSlices, slicesReceived);
}
}
else {
gotAllSlices = false;
file.closeAsync();
app.showNotification("getSliceAsync Error:", sliceResult.error.message);
}
});}
function onGotAllSlices(docdataSlices) {
var docdata = [];
for (var i = 0; i < docdataSlices.length; i++) {
docdata = docdata.concat(docdataSlices[i]);
}
var fileContent = new String();
for (var j = 0; j < docdata.length; j++) {
fileContent += String.fromCharCode(docdata[j]);
}}
你应该尝试一下这个。第一次收到响应时,您必须使用 file.closeAsync() 方法,然后每次需要时它都会工作
Office.context.document.getFileAsync(Office.FileType.Compressed, { sliceSize: 65536 },
function (result) {
if (result.status === "succeeded") {
const myFile = result.value;
myFile.getSliceAsync(0, function (result) {
let data = result.value.data
let btoadata = btoa(String.fromCharCode.apply(null, new Uint8Array(data)))
let fileobj = {
matterNumber: $scope.MatterNumber,
fileContent: btoadata
}
if (btoadata) {
myFile.closeAsync()
}
console.log(fileobj)
ProgressLinearInActive();
});
} else {
myFile.closeAsync()
// Handle the error here
loadToast("Upload Error");
ProgressLinearInActive();
}
}
);
